Physics Traditional: Unit 07 "Circular Motion, Torque & Simple Machines"

07- Circular Motion, Torque & Simple Machines
Summary: From what we know about motion, we know that acceleration happens in one of two ways: either you change the speed you're going, or you change the direction you're going. After all, acceleration is the rate of velocity change. However, acceleration is a vector and has a direction too. So, what is the direction of acceleration? You will find out this and more as you learn about circular motion. Here's another thing. Do you think they would ever build a door with a doorknob by the hinge? Would such a door be easy to open? The reason this is silly is because of torque – a concept you need to know, and we'll learn about here. Finally, we use simple machines all the time and you don't even realize it. All simple machines do is trade force for distance: you get a big force but you only get a small distance. You'll learn how that works in this unit too!
